The Moon? Boring. Mars? Meh. The next giant leap for mankind won't come in the form of an interplanetary trip, but rather a quest to the pile of rocks which weren't quite good enough to become planets. Yup, asteroids. And NASA's already started training for the trip.
The idea behind visiting an asteroid is that astronauts can explore the surface for minerals, and to gather knowledge about the oversized rocks should they ever end up en route to planet earth and need to be destroyed.
